Sunny with very warm air temperatures, feeling like 28 °C once we account for any wind. Sea temperatures (21 °C) warm too. Staying warm in the water won't be a problem in board-shorts, but wear at least a rash-vest to keep the UV off.

Cap Sim water temperatures peak in the range 20 to 23°C (68 to 73°F) on around the 12th of September and are at their lowest on about the 15th of February, in the range 16 to 19°C (61 to 66°F). Cap Sim water temperatures are highest in the second week of September. Surfers should use a 2mm long sleeve shorty or a 3/2mm spring wetsuit if the wind is up. The lowest seasonal water temperatures at Cap Sim in mid February lend themselves to a 4/3mm wetsuit or a 3/2mm suit and 3mm neoprene boots.
